    A Deliverable nuclear warhead section consists of the

    Warhead+Electronics+Guidance+Propulsion for initial maneuverability+Decoys.
    All of this make up the total warhead section weight which will be carried by the missile.

    Indian nuclear warhead weight

    Based on 1974 test design:-

    12kt Fission=500kg-700kg (Carriers-AGNI I,AGNI 2,PRITHVI-1,2)

    200kt Boosted Fission=800kg-1000kg (Carriers-AGNI I,AGNI 2,PRITHVI-1,2)


    Based on 1998 test design:-

    20kt Fission=250kg-450kg (Carriers-AGNI III,AGNI V,SAURYA)

    20kt Boosted Fission=100kg-300kg (Carriers-AGNI III,AGNI V,SAURYA)

    50kt Boosted Fission=300kg-500kg (Carriers-AGNI III,AGNI V,SAURYA)

    150kt Boosted Fission=450kg-650kg (Carriers-AGNI III,AGNI V,SAURYA)

    200kt Thermo Nuclear=300kg-500kg (Carriers-AGNI III,AGNI V,SAURYA)




    The AGNI III missile is more or less like a interim solution like the AGNI I-TD.

    The AGNI III missile is build with a throw weight of 2500 kg from ground up to make future missiles based on AGNI III missile MIRV capable.

    Now if we compare AGNI III missile with other missile of it's weight class and India's technological capabilities we can determine AGNI III missile's range and capabilities.

    AGNI III missile will be the base design for future AGNI's and will have inputs to the K-series missile,so we will compare AGNI III missile with both Land based missile and SLBM.

    Comparing AGNI III with UGM-133 Trident II,RSM-56 Bulava,M51 SLBM,RS-24 Yars,LGM-30G Minuteman-III.

    AGNI III AGNI-V Trident II Bulava M51 Yars Minuteman-III

    Weight: 48,000 kg 50,000 kg 58,500 kg 36,800 kg 52,000 kg 47,200 kg 35,300 kg

    Height: 17 m 17.5 m 13.41 m 12.1 m 12.0 m 23 m 18.2 m

    Diameter: 2.0 m 2.0 m 2.11 m 2.1 m 2.3 m 2.0 m 1.7 m

    Stage: 2 3 3 3 3 3 3

    Range: 3,500 km 5,000 km 11,300 km 10,000 km 10,000 km 11,000 km 13,000 km


    So we can see that in it's weight class AGNI III and AGNI-V has More Weight But Less Range.

    This happened due to 3 reasons:-

    1.Indian AGNI series and other missiles use Maraging Steel instead of composites used on other missiles which make them more weighty.

    Although recent use of composite stages has increased the range of AGNI 2 to 3,500 km from 2,500 km as recently seen in AGNI 4

    2.All other missiles use 1,600 kg payload to make them MIRV capable but since India doesn't

    have such miniaturization technology it had to use a bigger throw weight of 2,500 kg to

    make the missiles MIRV capable.

    3.The ranges of Indian missiles are de rated by Indian Government

    AGNI III should have a range of 5,500 km with full load of 2,500 kg.

    AGNI V should have a range of 7,500 km with full load of 2,500 kg.

    Although Indian missiles use Maraging Steel and high payload of 2,500 kg this ranges of AGNI III and AGNI V is achievable if we see in context of other missiles which are latest 4rt Generation missiles of Respective Countries.

    Indian SLBM K-15,K-4 are interim solution to create a full fledged SLBM which will be deployed in our SSBNs.

    Modern SSBNs use a VLS of Diameter of 2.2 m-2.4 m and length 12.0 m- 13.0 m.which is compatible to their SLBM diameter and length.If we also assume that our Arihant class SSBN have same VLS Diameter of 2.4m then we should expect a Indian SLBM of Diameter of 2.0 m-2.3 m and length of 12.0 m.

    If we use missile of more that 12.0 m- 13.0 m length then our SSBN will have a hump like DELTA-4 SSBN but since Arihant class SSBN doesn't have a hump we can assume that our SLBM which will be deployed will have alength of 12.0 m- 13.0 m.

    Now if we see the K-15 and K-4 missiles

    K-15 K-4 K-6

    Weight 10,000 kg 20,000 kg 38,000 kg

    Height 10 m 10 m 12 m

    Diameter 0.74 m 1.3 m 2 m

    Stage 2 2 3

    Payload 1,000 kg 1,000 kg 1,000 kg

    Range 750 km 3,500km 8,000km


    So we can see that K-15 and K-4 missiles are the same missiles with different diameter so they are test missiles not actual SLBM to be deployed.

    First deployable SLBM is K-6 with Length 12 m,Diameter 2 m,Payload 1,000 kg and Range of 8,000 km.

    Which will later be improved to a SLBM with Length 12 m,Diameter 2.0 m-2.3 m,Payload 2,500kg with MIRV and Range of 10,000 km which will be the Ultimate BRAHMASTRA.:india::india::india::india::india:

    India's first SLBM program has different project names to hid it from the public and media.Each time the media and the public got the sniff of the project the DRDO guys simply change the program name so that govt can deny their existence.The project names are
    PJ-08--SAGARIKA--K-15--B-05
    The name B-05 is given in 2010 and the production started in 2011.
    B-05 probably due to as in 2005 the missile for first conceptualized or launched.

    AGNI 4 is an updated version of AGNI 2 with removal of control wings(reduced drag) from 1st stage and the second stage of AGNI 2 replaced with a composite upper stage.
    The stage separation grill of AGNI 2 is not needed in the composite stage so it is removed which makes AGNI 4 1 m shorter tan AGNI 2
    Yet with light upper stage,reduces drag and only 1,000 kg increase in weight the range of the missile is increased from 2,500 km of AGNI 2 to 3,500 km of AGNI 4.
    Since AGNI 4 uses new warhead design so it should not need a 1,500 kg payload which will further increase its range.

    It is true that K15 is renamed again as B05.

    A SLBM testing has Different stages
    1.Pop-up test
    2.Flight test
    3.RV maneuverability test
    4.Full range Flight test

    All this tests are done on K15 missile and it's production started on 2011 for ARIHANT

    In 2010 the first test probably the pop up test was done for the K-4 missile of 3,500 km range test missile.

    Sir from your posts are you trying to say that the range of agnis are being played down?
    If so what is the strategy behind that, is it not better to claim that Agnis' range is near 8000km for deterance's sake?

    lets not make more enemy then what we already have, our requirement is about 5000-6000 km if you to attack whole of China from deep inside India. BTW when we can reach moon, then any spot in earth is not much of problem.

    On a lighter note, conventional wisdom suggests it is always better to play down your offensive capabilities so that when the enemy indeed receives the blow, it falls like a thunderbolt, out of the blue!

    though i agree to certain extent sir, i have a few objections. We should play down our strengths when we want a war but over hype our capabilities if we want to avoid one, atleast till we are ready to wage one, to keep the enemy confused and guessing. Atleast thats what Sun Tzu's Art of War says. So since we cant risk any war now we should keep our deterance to the max against anythin that is malignant towards us(even if it involves bluff). So if the govt is thinking about deterance i think its better for us if it kept the deterance high. Anyway thats just me:):)
    feel free to disagree:):)
